ENGINE COOLANT
TEMPERATURE GAUGE
 Normal range
The gauge indicates the engine coolant temperature when
the ignition switch is on. The engine operating
temperature will vary with changes in weather and engine
load.
If the needle points to the red zone or higher, stop your vehicle
and allow the engine to cool. Your vehicle may overheat during severe operating conditions,
such as:

Driving up a long hill on a hot day.
 Reducing speed or stopping after high speed driving.
 Idling for a long period with the air conditioning on in
stop−and−go traffic.
 Towing a trailer.
NOTICE
Do not remove the thermostat in the engine cooling
system as this may cause the engine to overheat. The
thermostat is designed to control the flow of coolant
to keep the temperature of the engine within the
specified operating range.
 Do not continue driving with an overheated engine.
See “If your vehicle overheats” on page 499.

TACHOMETER
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine overrevving.
Driving with the engine running too fast causes excessive
engine wear and poor fuel economy. Remember, in most
cases the slower the engine speed, the greater the fuel
economy.
NOTICE
Do not let the indicator needle get into the red zone. This
may cause severe engine damage.

(a) Brake System Warning Light and Buzzer
This light comes on in the following cases when the ignition key
is in the “ON” position.
 When the parking brake is applied...
This light comes on for a few seconds when the ignition key is
turned to the “ON” position even after the parking brake is
released.
If the vehicle speed rises above 5 km/h (3 mph) with the parking
brake applied, a buzzer sounds.
 When the brake fluid level is low...
CAUTION
It is dangerous to continue driving normally when the
brake fluid level is low.
Have your vehicle checked at your Lexus dealer in the
following case:
The light does not come on even if the parking brake is
applied when the ignition key is in the “ON” position.
 The light does not come on even if the ignition key is turned
on with the parking brake released. A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If either of the following conditions occurs, immediately
stop your
vehicle at a safe place and contact your Lexus
dealer.
 The light does not turn off even after the parking
brake is released while the engine is running.
In this case, the brakes may not work properly and
your stopping distance will become longer. Depress
the brake pedal firmly and bring the vehicle to an
immediate stop.
 The brake system warning light remains on together
with the “ABS” warning light.
In this case, not only the antilock brake system will
fail but also the vehicle will become extremely
unstable during braking.

(e) Charging System Warning Light
This warning light comes on when the ignition switch is turned
to the “ON” position, and goes off when the engine is started.
When there are problems in the charging system while the
engine is running, the warning light comes on.
NOTICE
When the charging system warning light comes on
while the engine is running, malfunctions such as the
engine drive belt being broken may have occurred. If
the warning light comes on, immediately stop the
vehicle in a safe place and contact your Lexus dealer.
(f) Low Engine Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the road
to a safe place and stop the engine immediately. Call a Lexus
dealer or qualified repair shop for assistance.
The light may occasionally flicker when the engine is idling or
it may come on briefly after a hard stop. There is no cause for
concern if it then goes out when the engine is accelerated
slightly.
The light may come on when the oil level is extremely low. It
is not designed to indicate low oil level, and the oil level must
be checked using the oil level dipstick.
NOTICE
Do not drive the vehicle with the warning light on —
even for one block. It may ruin the engine.

(g) Engine Oil Replacement Reminder Light (forvehicles sold in U.S.A.)
This light acts as a reminder when to replace the engine oil.
This light will come on when the ignition key is turned to the
“ON” position and will go off after about a few seconds.
When you drive for about 7200 km (4500 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to the “ON” position. If you continue driving
without replacing the engine oil, and if the distance driven
exceeds 8000 km (5000 miles), the light will come on after the
ignition key is turned to the “ON” position. The light will remain
on thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road conditions. If the light comes on, replace it as soon as
possible. The system must be reset after the engine oil replacement.
Reset the system by the following procedure:
1. Turn the ignition key to the “LOCK” position with the
odometer
reading shown. (For details, see “Odometer and trip
meter” on page 73.)
2. Turn the ignition key to the “ON” position while holding down
the “ODO/TRIP” button.
Hold down the button for at least 5 seconds. The odometer
indicates “000000” and the light goes off.
If the system fails to reset, the light will continue flashing.
